The root cause in this bug is that the connection info used by `SpdyConnectTransaction` is the same instance as the connection info in `nsHttpTransaction`, so we should clone it and let `SpdyConnectTransaction` use the cloned one.

Our telemetry data showed `WinUtils::GetNSWindowPtr` returned nullptr
when constructing `TaskbarTabPreview`.  We can't find a way to make such
a situation, but these crashes tell us we should not assume `GetNSWindowPtr`
always returns a valid pointer.

A proposed fix is to change the return value of `GetWindowHook()` from
a reference to a pointer so that the caller can decide what to do
when nullptr is returned.

For Big Sur toolbar search fields, don't return YES from _isToolbarMode(). And adjust the search field border for better spacing after the search icon.

Bug 1670358 - Don't use realloc for shrinking nsTArrays and similar when RelocationStrategy::allowRealloc is false. r=sg, a=tjr

My original patch handled the grow case but not the shrink case. When the
current and new allocation sizes are in different size classes jemalloc's
realloc will move the allocation when shrinking, not just truncate the existing
one.
